Abstract
The invention discloses antistatic corrugated board paint and a preparation method thereof. The antistatic corrugated board paint is characterized in that a conductive filler is positioned in a dry box and is dried to constant weight; a coupling agent is sprayed on the conductive filler, is sequentially added with film-forming resin, a mixed solvent and a dispersant and is evenly stirred to form a primary mixture; and the viscosity of the primary mixture after ball milling is regulated through a diluent for the ball milling of the primary mixture so as to obtain the antistatic corrugated board paint. The antistatic corrugated board paint has a more compact conductive structure to form a good interbedded communication structure and has a smoother conductive passage, thereby reducing the resistivity of the paint; the paint conducts through a few conduction mechanisms of a seepage theory, tunnel effect, a field emission theory and a thermodynamics theory; according to different proportioning proposals, the resistivity of the surface of the paint can be adjusted; the method has a simple and feasible process, convenient construction and lower cost, can improve production efficiency and does not generate influence on the prior performances of paperboard, such as mechanical performance and obstruction performance.
